Facts On Fish Anatomy! Trivia Quiz - Quiz

Fish is an aquatic gill-bearing animal that do not have limbs. In order to live, they must always be in the water, and breathe using their gill. During this quiz, you will be expected to learn what a vertebra is, what would happen to a fish if its swim bladder were injured, and what cartilaginous means. This quiz will tell you all about fish and their characteristics. Don’t neglect to take your certificate after the quiz.


Questions and Answers
  • 1. 

    Which of the following is a vertebrate?

    • A.

      Squid

    • B.

      Beetle

    • C.

      Cat

    • D.

      Lobster

    Correct Answer
    C. Cat
    Explanation
    A vertebrate is an animal that has a backbone or spinal column. The cat is a vertebrate because it belongs to the class of mammals, which are characterized by having a well-developed backbone. Squid, beetle, and lobster are all invertebrates, meaning they lack a backbone and therefore are not vertebrates.

    Why aren't humans considered ectothermic?

    • A.

      Because our body temperatures generally stay the same in all conditions.

    • B.

      Because we give birth to live young.

    • C.

      Because we have skeletons made of bone, not cartilage.

    • D.

      Because we can't breathe under water.

    Correct Answer
    A. Because our body temperatures generally stay the same in all conditions.
    Explanation
    Humans are considered endothermic, not ectothermic, because our body temperatures generally stay the same in all conditions. Ectothermic animals, such as reptiles, rely on external sources of heat to regulate their body temperature, while endothermic animals, like mammals, can internally generate and regulate their body temperature. The fact that humans can maintain a constant body temperature independent of external conditions distinguishes us from ectothermic animals.

  • 3. 

    In the sentence, "Fish gills are analogous to human lungs," what does"analogous to" mean?

    • A.

      Less evolved than

    • B.

      Exactly the same as

    • C.

      Diffrent than

    • D.

      Comparable to

    Correct Answer
    D. Comparable to
    Explanation
    The phrase "analogous to" means that fish gills and human lungs have similarities or similarities in function. They are not exactly the same, but they can be compared or seen as similar in some ways.

  • 4. 

    What can you infer about cartilaginous fish from the size of their brains?

    • A.

      On the whole, they're more intelligent than other vertebrates.

    • B.

      On thewhole, they're less intelligent than bony fish.

    • C.

      On the whole, they're more intelligent than bony fish.

    • D.

      On the whole, they're less intelligent than invertebrates.

    Correct Answer
    C. On the whole, they're more intelligent than bony fish.
    Explanation
    Based on the given information, it can be inferred that cartilaginous fish are more intelligent than bony fish. This inference is made based on the statement "on the whole, they're more intelligent than bony fish." Therefore, the size of their brains suggests that cartilaginous fish have higher intelligence compared to bony fish.

  • 5. 

    Just as fish have fins, boats and airplains have finlike structures. What can you conclude about the purpose of fins?

    • A.

      They're the most important part of a fish'es body.

    • B.

      They're used to reduce the weight of flying and swimming objects.

    • C.

      They guide the movement of objects throught the water.

    • D.

      They prevent both fish and boats from sinking.

    Correct Answer
    C. They guide the movement of objects throught the water.
    Explanation
    Fins are mentioned as a similarity between fish, boats, and airplanes. The purpose of fins is not stated explicitly, but based on this information, it can be concluded that fins guide the movement of objects through the water. This is because fish use fins to navigate and maneuver in the water, and boats and airplanes also have finlike structures that help control their movement through the water or air.

  • 6. 

    In the sentence, "A fish's streamlined body helps it move through the water," what is the best synonym for "streamlined"?

    • A.

      Scaly

    • B.

      Sleek

    • C.

      Wet

    • D.

      Wide

    Correct Answer
    B. Sleek
    Explanation
    In the given sentence, "A fish's streamlined body helps it move through the water," the best synonym for "streamlined" is "sleek." This is because "sleek" means smooth, streamlined, and elegant, which accurately describes the body of a fish that is designed to move efficiently through the water.

    Rate this question:

  • 7. 

    What might happen to a fish if its swim bladder were injured?

    • A.

      It couldn't move forward throught the water.

    • B.

      It couldn't rigulate its depth in the water.

    • C.

      It couldn't breathe under water.

    • D.

      It couldn't release waste from its body.

    Correct Answer
    B. It couldn't rigulate its depth in the water.
    Explanation
    If a fish's swim bladder were injured, it would not be able to regulate its depth in the water. The swim bladder is an organ that helps fish control their buoyancy and stay at a certain depth in the water column. If the swim bladder is injured, it may not function properly, causing the fish to have difficulty maintaining its desired depth. This could result in the fish floating to the surface or sinking to the bottom, depending on the severity of the injury.

  • 8. 

    Which of the following is an opinion about fish?

    • A.

      There are more fish species than the mammal species.

    • B.

      The mouths of lampreys are strange looking.

    • C.

      Fish can be found in both freshwater and saltwater habitats.

    • D.

      Many species of fish eat other fish to survive.

    Correct Answer
    B. The mouths of lampreys are strange looking.
    Explanation
    The given statement "The mouths of lampreys are strange looking" is an opinion about fish because it expresses a subjective judgment about the appearance of a specific feature of lampreys, which are a type of fish. Opinions are personal viewpoints and can vary from person to person, unlike factual statements that can be objectively proven or disproven. In this case, the statement reflects the speaker's perception of lamprey mouths, making it an opinion.

    Rate this question:

  • 9. 

    Which word best describes cartilanginous fish?

    • A.

      Boneless

    • B.

      Vegetarian

    • C.

      Slow

    • D.

      Warm-blooded

    Correct Answer
    A. Boneless
    Explanation
    Cartilaginous fish are described as "boneless" because their skeletons are made of cartilage instead of bone. This allows them to be more flexible and agile in the water. Unlike bony fish, which have a skeleton made of hard bone, cartilaginous fish, such as sharks and rays, have a more flexible and lightweight structure. This adaptation enables them to swim efficiently and navigate through their aquatic environment with ease.

  • 10. 

    What can a shark do that a lamprey can't?

    • A.

      Eat meat

    • B.

      Breathe underwater

    • C.

      Regulate its depth in the water

    • D.

      Chew its food

    Correct Answer
    D. Chew its food
    Explanation
    A shark can chew its food, while a lamprey cannot. Sharks have strong jaws and multiple rows of sharp teeth that allow them to tear and chew their prey. On the other hand, lampreys are jawless fish that attach themselves to other fish and suck their blood, so they do not need to chew their food.
